10 Healthy Food Swaps for Losing Weight

Lighten up your mayo.

Swapping your regular mayonnaise for a lower-fat version can save significant calories. Light mayonnaise reduces calories per tablespoon to 35 or so, and total fat to between 3 and 4 grams per serving. Low-fat or reduced-fat varieties usually cut calories and fat to 15 and about 1 gram, respectively.

Going from 90 calories per tablespoon to 15 is a significant reduction, and when it comes to losing weight over the long term, these are the kinds of changes that really add up.
